  • ad28a07bc   rtc: fix platform driver hotplug/coldplug ... Browse Code »

    Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is
    prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable RTC
    platform drivers, to re-enable module auto loading.

  • a4b1d50e6   RTCs: handle NVRAM better ... Browse Code »

    Several of the RTC drivers are exporting binary "nvram" files in sysfs. Such
    NVRAM (or on many systems, EEPROM) data is often initialized during system
    manufacture to hold data about identity (serial numbers, Ethernet addresses,
    etc), configuration, calibration, and so forth.

    This patch improves integrity and security of those files:

    - Correctly initializes the size in one of the two cases where
    that was not yet being done.

    - Improves system security/integrity by making this state not
    be world-writable by default.

    Letting arbitrary userspace code mangle such state by default is at least Not
    A Good Thing; and it could sometimes be worse, depending on the particular
    data that might be corrupted. (I disregard the paranoiac "don't let anyone
    read it either" approach. Anyone storing passwords in such memory doesn't
    really care about security.)

  • c98dbe59a   fix missing arguments in drivers/rtc/rtc-stk17ta8.c ... Browse Code »

    struct bin_attribute * is needed in bin_attribute ->read()/->write()
    now. Incidentally, could people please run the fscking compiler
    before and after applying their patch and compare the build logs?
    That (and many, many other) would be caught immediately.

  • 029641151   rtc: add support for STK17TA8 chip ... Browse Code »

    This patch adds support for the Simtek STK17TA8 timekeeping chip.

    The STK17TA8 is quite similar to the DS1553, but differs in register layout
    and in various control bits in the registers. I chose to make this a new
    driver to avoid confusion in the code and to not get lost in #ifdefs.
